LAUNCH X-431 Torque III User Manual
The tested system with fault code appears in red and the system with OK
displays in black (normally).
Note: Diagnostic Trouble Codes or Fault Codes can be used to identify which engine
systems or components that are malfunctioning. Never replace a part based only on the
DTC definition. Retrieving and using DTCs for troubleshooting vehicle operation is
only one part of an overall diagnostic strategy. Follow testing procedures (in vehicle's
service manual), instructions and flowcharts to confirm the locations of the problem.
